PumpView Buy Score Explained: How It Actually Works
PumpView’s Hot Tokens tab ranks every tracked Solana token with a Buy Score. If you’re trading memecoins on Pump.fun, PumpSwap, Raydium, or Meteora, understanding this score is the difference between chasing noise and focusing on real momentum.
On the PumpView homepage and FAQ, the Buy Score is described as a 0–9 composite score built from eight real‑time signals: buy volume dominance, market‑cap‑to‑volume ratio, multi‑DEX presence, 10‑second price trend, net 30‑second buy pressure, transactions per second, launchpad type, and wash trading impact. (pumpview.fun)
This article breaks down each of those components in practical trading terms and shows how to combine Buy Score with other on‑chain tools like Birdeye, DexScreener, and Solscan.
What the PumpView Buy Score Is (and Isn’t)
What it is:
- A real‑time momentum and quality score for each token, updated continuously from live DEX trades.
- A way to rank tokens relative to each other based on current buying pressure and market structure.
- A composite of 8 measurable signals derived from on‑chain swaps and token metadata.
What it isn’t:
- Not a guarantee of future returns.
- Not a fundamental valuation metric (it doesn’t care about roadmaps or teams).
- Not a replacement for your own risk management.
You should treat Buy Score as a short‑term trading radar, not an investment thesis.
The 8 Signals Behind Buy Score
According to PumpView’s own documentation, the Buy Score (0–9) is computed from these eight signals: (pumpview.fun)
- Buy volume dominance
- Market‑cap‑to‑volume ratio
- Multi‑DEX presence
- 10‑second price trend
- Net 30‑second buy pressure
- Transactions per second (token‑level activity)
- Launchpad type
- Wash trading impact
PumpView doesn’t publicly disclose the exact weighting formula, but we can still use each component intelligently.
1. Buy Volume Dominance
What it measures:
- The share of buy volume vs sell volume for a token over a short recent window.
- If most of the traded volume is buys, buy dominance is high; if it’s mostly sells, it’s low.
Why it matters:
- High buy dominance usually means net inflows into the token right now.
- Low or negative dominance means distribution or exit liquidity.
How to use it:
- High Buy Score + strong buy dominance → short‑term momentum is aligned with the score.
- High Buy Score but buy dominance dropping → momentum may be topping out; consider tighter risk controls.
You can cross‑check this on DexScreener or Birdeye by looking at recent trade lists and buy/sell volume bars for the same token.
2. Market‑Cap‑to‑Volume Ratio
What it measures:
- A simple ratio: fully diluted or current market cap vs recent trading volume.
- A low MC/Vol ratio means the token is trading a lot relative to its size; a high ratio means little volume for the valuation.
Why it matters:
- Low MC/Vol can indicate healthy liquidity and interest for a given cap.
- Extremely high MC/Vol often flags stale or illiquid tokens where entering and exiting size is harder.
How to use it:
- Prefer tokens where Buy Score is high and MC/Vol is not extreme.
- If a token has a decent Buy Score but MC/Vol is very high, treat it as fragile momentum.
You can verify market cap and volume on Birdeye or DexScreener by checking the token’s market cap, 24h volume, and liquidity.
3. Multi‑DEX Presence
What it measures:
- Whether a token is trading on more than one venue (e.g., Raydium + PumpSwap + Meteora) vs being isolated to a single pool.
Why it matters:
- Multi‑DEX presence usually correlates with:
- More organic discovery (different trader bases).
- Better liquidity routing via aggregators like Jupiter.
- Lower risk of being a one‑pool honeypot.
How to use it:
- Tokens with multi‑DEX presence and a strong Buy Score are generally higher quality momentum than single‑pool microcaps.
- Confirm venues on Jupiter, DexScreener, or Birdeye by checking the list of pools and DEXes for that token.
4. 10‑Second Price Trend
What it measures:
- The very short‑term price direction over roughly the last 10 seconds.
- Think of it as a micro‑trend: are trades pushing price up or down right now?
Why it matters:
- On Solana, blocks are fast and memecoins move quickly. A 10‑second trend can:
- Confirm that momentum is currently accelerating.
- Warn you if price is stalling or reversing even while volume remains high.
How to use it:
- When sniping new launches, combine:
- High Buy Score
- Positive 10‑second trend
- Reasonable gas/priority fees (check your wallet or Jito‑powered RPC)
- If the 10‑second trend flips negative while you’re entering, consider scaling in smaller or waiting.
You can see similar micro‑price behavior on DexScreener by watching 1‑second or tick charts where available.
5. Net 30‑Second Buy Pressure
What it measures:
- The net effect of buys minus sells over ~30 seconds, usually in volume terms.
Why it matters:
- A single big buy can spike price briefly, but sustained net buy pressure over 30 seconds signals ongoing demand, not just one whale.
How to use it:
- Look for tokens where:
- Buy Score is high
- Net 30‑second buy pressure is positive and stays positive across multiple windows
- If Buy Score is high but 30‑second net pressure keeps flipping negative, you may be late to the move.
On PumpView, this is reflected in the Hot Tokens metrics and the Early Scanner bubble behavior (bubble color and ring indicating net buy/sell pressure). (pumpview.fun)
6. Transactions Per Second (Token‑Level Activity)
What it measures:
- The rate of trades per second for a specific token, not the whole Solana network.
Why it matters:
- Higher token‑level TPS usually means:
- Tighter price discovery
- More opportunities to enter/exit without moving the market too much
- Stronger confirmation that the move is broadly participated, not just a few big wallets
How to use it:
- For scalping or very short‑term trades, prioritize tokens with high Buy Score and elevated token TPS.
- Combine with network‑wide TPS (PumpView’s Solana TPS tab) to avoid entering during network congestion when transactions may fail or be delayed. (pumpview.fun)
You can also cross‑check token activity on Helius or Solscan by looking at recent swap transactions for the token’s main pool.
7. Launchpad Type
What it measures:
- The origin of the token: Pump.fun bonding curve, Raydium launchpad, Meteora pools, etc. PumpView explicitly tracks Pump.fun, PumpSwap, Raydium (AMM/CPMM/CLMM), RayLaunchpad, and Meteora variants. (pumpview.fun)
Why it matters:
- Different launchpads have different mechanics and risk profiles:
- Pump.fun: bonding‑curve launches that migrate to PumpSwap after hitting a liquidity threshold. (levex.com)
- Raydium / RayLaunchpad: more traditional AMM or launchpad structures, often with deeper liquidity once live.
- Meteora: dynamic and concentrated liquidity designs that can change how price reacts to volume.
How to use it:
- If you specialize in Pump.fun meta, you may accept higher risk on fresh bonding‑curve tokens but want very strong Buy Score + low wash.
- For larger size trades, you might prefer tokens that graduated to Raydium or Meteora with better liquidity depth.
You can verify launchpad and pool details on DexScreener, Birdeye, or directly on Pump.fun for bonding‑curve coins.
8. Wash Trading Impact
What it measures:
- How much the token’s activity looks like fake or coordinated volume. PumpView computes a separate Wash Score (0–100%) using four signals: same‑wallet round trips, top‑5 wallet concentration, repeat trading frequency, and unique wallet count. Tokens with high Wash Score are penalized in Buy Score. (pumpview.fun)
Why it matters:
- Wash trading can:
- Inflate volume and make a token look “hot” on generic scanners.
- Create fake buy dominance that collapses once the wash stops.
How to use it:
- Focus on tokens where:
- Buy Score is high
- Wash Score is low (PumpView suggests that tokens with Wash Score above ~50% are suspicious and get penalized). (pumpview.fun)
- If a token looks great on other sites but has high Wash Score on PumpView, treat it as likely manufactured volume.
You can cross‑check wallet concentration and trade patterns on Solscan, Birdeye (holders tab), or Helius APIs.
How to Read Buy Score in the Hot Tokens Tab
PumpView’s Hot Tokens tab doesn’t just show Buy Score. It also surfaces:
- 1‑minute and 5‑minute candle price changes
- A green candles counter (0–5) showing how many of the last five 1‑minute candles closed green
- Volume, market cap, wash %, and other real‑time stats (pumpview.fun)
Here’s how to combine them:
Strong Momentum Setup
Look for tokens with:
- Buy Score ≥ 7
- Wash Score low (e.g., below ~20–30%)
- Multiple consecutive green candles (green candle counter ≥ 3)
- Positive 1m and 5m price change
This combination suggests sustained organic buying, not just a single spike.
Exhaustion / Late Entry Warning
Be cautious when you see:
- High Buy Score but
- Green candle counter at 4–5 and
- 1m price starting to flatten or turn red
- Wash Score creeping up
This can mean you’re entering after an extended push, where early buyers may start taking profits.
Fake Heat Filter
Avoid or size down when:
- Buy Score is only moderate, but
- Wash Score is high
- MC/Vol looks unnatural (very high cap, low real volume)
On other scanners, this might still appear as a “trending” coin; PumpView’s Buy Score plus Wash Score helps you filter that noise.
Practical Workflow: Using Buy Score with Other Tools
Here’s a concrete way to integrate PumpView Buy Score into your Solana trading flow:
- Start on PumpView Hot Tokens
- Sort by Buy Score and then filter by your preferred market cap range.
-
Ignore tokens with very high Wash Score unless you’re intentionally trading short‑lived pumps.
-
Open the token on DexScreener or Birdeye
- Check liquidity size, FDV/MC, and pool depth.
-
Confirm that the price action you see there matches the 1m/5m candles from PumpView.
-
Check on Solscan / Helius
- Inspect top holders and recent transfers.
-
Look for dev wallets, large unlocks, or suspicious concentration.
-
Confirm venue and routing on Jupiter
- See which pools Jupiter uses for routing.
-
If the token is only on a single tiny pool, adjust size or skip.
-
Decide entry & risk
- Use Buy Score and its components as a timing and quality filter, not as your only signal.
- Set clear stop levels and size limits based on liquidity and volatility.
Limitations and Best Practices
Even with a sophisticated composite like Buy Score, there are important limitations:
- Short‑term only: The signals are built from seconds‑to‑minutes windows. They don’t tell you anything about long‑term fundamentals.
- Sensitive to Solana conditions: During network congestion or priority fee spikes, some signals (like token TPS) may be distorted.
- Programmatic traders adapt: Once many traders key off the same metrics, some actors may try to game the signals (e.g., spoofing buys that don’t hold).
Best practices:
- Use Buy Score as a first filter, not a final decision.
- Always cross‑check liquidity, holder distribution, and contract risk on external tools.
- Size positions assuming fast reversals are possible, especially on fresh Pump.fun launches.
Conclusion: Treat Buy Score as Your Real‑Time Radar
PumpView’s Buy Score condenses eight on‑chain signals into a single 0–9 number so you can quickly see where real buying is happening right now across Pump.fun, PumpSwap, Raydium, and Meteora. (pumpview.fun)
By understanding what each component measures — buy dominance, MC/Vol, multi‑DEX presence, micro‑price trends, net buy pressure, token TPS, launchpad type, and wash trading impact — you can:
- Focus on high‑quality momentum instead of noisy pumps
- Avoid many wash‑traded or illiquid traps
- Combine PumpView with tools like DexScreener, Birdeye, Solscan, Helius, and Jupiter for a complete picture
Used correctly, Buy Score is not a magic “buy” button — it’s a real‑time radar that helps you decide which tokens deserve your attention right now, and which ones to ignore.
